马铃薯A病毒的研究进展

Research Progress in Potato Virus A

马铃薯A病毒(Potato virus A,PVA)作为主要病毒之一,对马铃薯种薯质量有着十分重要的影响。近年来,PVA的研究已从传统生物学研究转向了基因组的研究,基因组编码的蛋白在基因组复制、蛋白加工和系统移动等方面具有重要作用。目前国内外对于PVA的研究主要集中在检测方面,而蛋白功能的研究较少且还处于初级阶段,随着国内PVA发病率的升高和马铃薯产业需要,深入了解PVA基因组蛋白的功能及挖掘抗性基因资源、拓宽遗传背景对于揭示PVA致病机制、寻找抗病途径、促进产业发展具有重要意义。

As one of the main viruses,potato virus A(PVA)has a very important impact on the quality of potato seed tubers.In recent years,PVA research has turned from traditional biological research to genome research.The proteins encoded by the genome play an important role in genome replication,protein processing and system movement.At present,the researches on PVA at home and abroad mainly focus on detection,while the research on protein functions is still in the initial stage.With increasing incidence rate of PVA and the needs of potato industry in China,deeply understanding the function of PVA genomic proteins,mining resistance gene resources,and broadening the genetic background will have great significance for revealing the pathogenic mechanism of PVA,finding ways to resist disease and promoting industrial development.
